ROSS 308 AP PARENT STOCK: Performance Objectives

2017

Introduction

This booklet contains the performance objectives for the Ross® 308 AP Parent Stock and is to be used in conjunction with the Ross Parent Stock Management Handbook.

Performance

Poultry production is a global activity, but across the world there are differing management strategies adapted to local conditions. These performance objectives are specifically for poultry producers in Latin America. The advice provided is therefore relevant to the management strategies employed within the Latin American region. However, the recommendations given are useful and informative for other world regions.

These performance objectives are for birds that receive the first light stimulation after 21 weeks (147 days) of age. This is the most common strategy used worldwide as it gives distinct advantages in early egg size, chick numbers, and broiler chick quality.

Achieving the genetic potential of the birds depends on:

• Management to provide birds with their required environment.

• A dietary regime that provides the appropriate nutrients.

• Effective biosecurity and disease control.

If any one of these elements is sub-optimal performance will suffer. The three sectors - environment, nutrition and health - are also interdependent; a problem in any one will result in a negative response by the bird to the other factors.

Data contained within this booklet indicates the performance that can be achieved under good management and environmental conditions and when feeding the recommended nutrient levels. They should be therefore regarded as “Performance Objectives” and not specifications. In practice, variations in performance may occur for a wide variety of reasons. For example, feed consumption can be affected significantly by feed form, energy level and house temperature.

While every attempt has been made to ensure the accuracy and relevance of the information presented, Aviagen® accepts no liability for the consequences of using this information to manage parent stock.

All weight measurements are shown in both metric (kg/g) and imperial (lb/oz) to reflect the global nature of this publication.

In the tables, values are rounded. This may result in small inaccuracies when using the objectives to calculate other performance statistics.

For further information on the management of Ross stock, please contact your local Ross representative.

KEY (kg/g) – metric measurement (lb/oz) – imperial measurement

NOTES:

Body weights are those 4-6 hours after feeding.

Weekly body-weight gain beyond 30 weeks (210 days) should average approximately 15-20 g (0.03-0.05 lb).

*Feed quantities are given as a guide only, based on recommended dietary energy levels of a 2- or 3-stage rearing program (2800 kcal ME/kg; 1270 kcal ME/lb). Adjustments must be made

to reflect feeding differing energy levels.

NOTES:

Daily energy and feed intakes are based on current recommended dietary levels of energy(2800 kcal ME/kg; 1270 kcal ME/lb) and assuming an ambient temperature of 20 - 21oC (68 - 70oF).

*Feeding programs should be adjusted according to actual feed intake at 5% hen-day production. It may be necessary to adjust feed amounts daily (rather than every 5% as given in the table), taking into account the rates of daily production. Adjustments to feed amounts will need to be made if dietary energy levels are different to those recommended or if environmental temperatures are warmer or cooler than assumed here.

KEY (kg/g) – metric measurement (lb/oz) – imperial measurement

NOTES:

Body weights are those 4-6 hours after feeding.

This profile allows the male to reach sexual maturity by first egg. Weekly body-weight gain beyond 30 weeks (210 days) should average approximately 30 g (0.06-0.07 lb).

Field performance has shown that this practice ensures that the body condition of the males is not compromised so they will maintain the best possible fertility levels.
